SWITCH-CLAMP BRACKET.

Application filed April 21, 1926. Serial No. 103,491.

This is an invention relating to brackets to be attached over the edgeof a supporting member as a means of holding some object to bedetachably fixed to the bracket, and the as a means for quicklyattaching an electric switch to the instrument board of an automobilewithout having to boreholes or apply screws.

Referring to the accompanying drawing,

Fig. 1, is a front elevation of the bracket as mounted on a section ofan instrument board;

Fig. 2, a side elevation of a modification of the bracket;

Fig. 3, a front elevation of a modification of the bracket;

Fig. 1, a side elevation of the bracket as shown in Fig. 3;

Fig. 5, a front elevation of fication of the bracket;

Fig. 6, a side elevation of the bracket shown in Fig. 5;

Fig. 7, a side elevation of a slight modification of the bracket asshown in Figs. 1 and 2.

Like characters of reference indicate like parts throughout the variousviews.

Referring to Figs. 1, 2, and 7, the bracket is comprised of two plates afront plate having its upper portion adapted to extend up on and lieflatly against the board 11, and the plate 10 depends below the boardand has its lower end turned backwardly;

a second modiand a rear plate 12, having an upper portion adapted tocontact the board 11 from behind, a central portion bent forwardly fromthe upper portion, and a lower portion depending from the front of thecentral portion with its lower end turned forwardly to approach thebackwardly turned edge of the front plate 10. Each of the two dependingportions of the plates 10 and 12 has a hole therethrough to receive thestem 13 of the switch 14, the switch 14 being one form that is commonlyemployed where all parts are to be concealed behind the board 11 withonly a switch operating button 15 being visible.

A look nut 16 is carried on the stem 13 to contact the plate 10 from thefront and a lock nut 17 is also carried on the stem 13 to contact theplate 12 from behind, and by running these lock nuts 16- and 17 uptightly against the plates, the platesare drawn toward eachother to gripthe board 11 therebetween by the upper portions of the plates, and toincreasecthis grip, the lower ends of the plates are made to contact oneanother. as at (1, whereby the nuts 16 and 17 increasesthe leverage ofthe plates on the board 11.

Should the board 11 not beuniform in thickness in all cases, so that thelower ends of the plates 10 and 12 contact before plates are tightlyagainst the board 11, a thumb screw 18 is provided in the upper portionof the back plate 12 and carries the bearing increased tightening ofROBERT C. PISCATOR, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO Q'C FALITYPLATING I foot 19, whereby the thumb screw may be press the foot 19against the board 7 and thereby cause the bracket to In Figs. 3 and 1,the bracket is formed with the front and back plates 20 and21 integrallyunited at the lower end, the bracket here shown as 21 turned backwardlyand upwardly against the back of the front plate 20 to the under edge ofthe board 11 thence-backwardly and upwardly behind the board to carrythe thumb screw 18 as the means of clamping the bracket to the board11.. The switch 1a is carried by its stem 13 and lock nuts 16 and 17 intions of the plates. I v I Figs. 5 and 6 illustrate a. furthermodification of the bracket in that the rear plate 22 is attached to thetop edge of the front plate 28, lies between theboard 11 and extendsdown and up around behind the board 11 to carry the clamping thumb screw18.

I claim:

In combination with a, supporting member and an object having a stem, aplate in front of the said supporting member; a plate in rear of saidsupporting member; a section of each of said plates depending from thesaid member, said sections having their lower ends formed to approacheachother and having a passage therethrough to receive said stem; andlocknuts on the stemto be drawn up against said sections, and screwmeans carried by the rear plates to grip the supporting member againstthe front plate.

In testimony whereof I aflix my signature.
